Used in pharmaceutical synthesis as an intermediate for developing biologically active compounds, particularly in the production of kinase inhibitors and other therapeutic agents targeting inflammatory and oncological diseases. Its structure supports the formation of heterocyclic frameworks common in drug design. Also employed in research settings for derivatization and labeling due to its reactive amidine functionality, enabling conjugation with biomolecules or probes. Solubility in polar solvents makes it suitable for solution-phase reactions in medicinal chemistry workflows.
